Hi All, as I’m having difficulties identifying the issue I thought I would ask the pros on the forum

The car is an N reg 1.1 Cinquecento Sporting SPI, standard as far as the engine bay goes. I recently gave it a mini service (oil filter & oil, air filter, clutch kit and a genuine stepper motor as it was hunting) but still when driven steady in gear at 30-40mph it will start yanking/pulling until you start accelerating more. Same if you are in traffic trying to move along steady in first or second at low speed it will keep yanking/pulling so I need to accelerate and put it in neutral to roll –very frustrating!

What may be the cause of this? It has no air leaks. Could it be the lambda sensor?

Vac pipes wrong way round or possibly a map sensor

You still got the baby ferrari?

Oh yes, had my little Ferrari for nine years now and covered 100k in it, still going strong minus this pain in the backs side

So where do I find those vac pipes?

Fitted a new genuine MAP sensor today and no change :/ any idea which are the vac pipes?

From what I can remember mate they are on the back of the inlet
